DNS and MX records

Anyone know what this one means when doing a nslookup:<br>I'm curious of why it says &quot;Non-authoritative answer&quot;<br><br>C:\&gt;nslookup<br>Default Server:&nbsp;&nbsp;dns.domain.com<br>Address:&nbsp;&nbsp;195.1.1.1<br><br>&gt; set type=mx<br>&gt; email.com<br>Server:&nbsp;&nbsp;dns.domain.com<br>Address:&nbsp;&nbsp;195.1.1.1<br><br>Non-authoritative answer:<br>email.com&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;MX preference = 1, mail exchanger = mail.email.com<br><br>mail.email.com&nbsp;&nbsp;&nbsp;&nbsp;internet address = 196.1.1.1<br>&gt;<br><br>Regards<br><br>Lars

I'm no expert on DNS, but I believe the Non-authoritative response comes from the secondary DNS server, or not the &quot;Authoritative&quot; (primary) DNS server. <p>Al<br><a href=mailto: atc-computing@home.com> atc-computing@home.com</a><br><a href= > </a><br>

It could also mean this information is cached in which the answer is not provide by the Zone authority.<br> <p>Doug<br><a href=mailto:dxd_2000@yahoo.com>dxd_2000@yahoo.com</a><br><a href= > </a><br>

The Domain Name Server that you are querying is not the SOA for that domain name. Your response that you get may have the IP address and name of the server that is SOA for the domain name you are asking about..

example:
You can then try doing an ns lookup with
&quot;server ns.kivex.com&quot;

then you will be querying the server that is SOA, not your defaul domain name server.
